Quick and dumb question

I was re-reading my chapter one where my MC wakes up in a hospital to the sound of a radio playing in the room. Only the thing is, I mention it with a brief italicized quote from the radio announcer, then something long the lines of :

Where is that voice coming from? What’s going on here? Are they trying to talk to me?
Wait a minute. Is that Dean Martin?
Son of a bitch, I must have passed out with the radio on or something.

But after this, I notice I never mention the radio again. Not seeing it, hearing it anymore, anyone turning it off. Am I blowing this out of proportion, or is there even any need to mention it again, even in a small sense like the doctor switching the set off?

The radio was on, now it's off. Why would you keep mentioning the radio if it has no further part in the story? Is it a magic radio that keeps turning itself on sending subliminal messages to your character? If not, forget it.

If you noticed it and it slightly bothered you, perhaps there is something about it that feels odd. I see sometimes,with some writers, they anchor the situation by mentioning a superficial detail. Originally it involves something plot advancing (in your case the character waking up confused, hearing the radio) and then towards the end of the scene, they refer to that (radio) as if to close the issue or reveal another piece of information. It makes things feel familiar for the reader and it draws them in. I'm probably not explaining it right, but by mentioning the detail later on, it gives sense of closure and reality. So maybe you should refer to what happened to the radio by the end of the scene, and see if it works.
